Haha yes I’m stumped as well! So when it comes to testing with the Hanna checker it’s a yes to everything except the 10ml syringe. I’ve been filling to the line because my 10ml syringe must not be accurate it always goes over the line on the glass. So I’ve been just filling to the line. Other then that yes it’s the same reagent bottle, I wipe clean finger prints, the 1ml reagent stays in the tip.
